       Hi,

       These are more htword cosmetic changes. Plus a bug fix. The WordType
instance was not initialized soon enough, that triggered some memory corruption
in some cases. I took advantage of this fix to simplify WordContext a lot.
make distcheck is on the way.

       Cheers,

        * htword/WordContext.h (class WordContext): simplifies a lot. WordContext is
          no longer a repository for pointers of class instances. Only a place to call
          Initialize for classes that have a single instance.

        * htlib/HtWordType.cc: added to include definition of functions shortcuts for
          WordType.

        * htword/WordRecord.h,WordType.h,WordKeyInfo.h: implement homogeneous scheme to
          handle unique instance of the class.
          - constructor takes const Configuration& argument and init object with config
            values
          - static member instance
          - static method Initialize the static member instance
          - static method Instance returns the pointer in instance data member
        
        * htword/WordRecord.cc: add constructor for WordRecordInfo, and Instance static
          function. Add WORD_RECORD_INVALID to depict uninitialize WordRecordInfo object.

        * htword/WordKeyInfo.h: rename SetKeyDescriptionFromFile and SetKeyDescriptionFromString
          to InitializeFromFile and InitializeFromString and implement them by calling Initialize.
          rename SetKeyDescriptionRandom to InitializeRandom
          rename Initialize(String& line) to GetNFields(String& line)
          rename Initialize(int nfields) to Alloc(int nfields)

        * htdig/htdig.cc,htmerge/htmerge.cc,htsearch/htsearch.cc,test/word.cc: replace
          WordList::Initialize with WordContext::Initialize and run immediately after
          config is read. Otherwise WordType fails to work and configuration value
          extraction will fail.

        * htmerge/htmerge.cc: move initialization

        * test/conf/htdig.conf2.in: reorder so that it looks as much as possible as conf.in
